Referring more inhdetail to :the? drawing, the present marking gaugeembodies wan elongated-sheet .meta-l or other suitable abar 5hav-- 'inga:straightrlongitudinal marking edge 6 and provided-witlrend portions '1bent at right angles to' the mainibbdy portion to: form contactszorfabutments toiengagez an; edgeiof a board or casing member towhich-the board .abutments 7. are inithesameg' plane as c t-he straightedge, 6 of the-bar .5, :andsaid abut- ,ments 7 are, provided'withi'nturned' terminal flanges 9 so as to havemoreeffect-We and firmcontact with: the :casing.

i The gange constructed-as thus -,fan described; is suitable for;severlalmnethods 1 of use,-examplesof-zw h'ich are: shown in Ei-gures- 5and 6. --In'E;i-gu-re 5 the gangeis. illustrated in use for ma-rlri ngthe linefor cutting a'base board 12 for-fitting itbetweenthe corner of a13 of adoorcasingor'frame having azstrai'ght edge lLconti-nuecb to thefloor of the room. In this use,-the endi0i the-base board r12w-hich isnot shown is; temporarily iengaged'with' the preceding section oivbaseboardnat a corner of the room. \vhiletheend of. the base-board 12which-is shown isplaced against the lower end of the side casing member,13as.illustrated. The bar 5 is previously placedacross the base boardwith the fixeduend 1 abutments projectingabeyond"saidbaseboardatthe 20The marking bar is then laid across the upof a door frame isoftenconstructed at its opposite edges of the latter as shown, the bar 5being of greater lengththan the width of the board 12 to permit thispositioning of the gauge. The gauge is then forced toward the sidecasing member 13 until the edges 8 of the abutments 7 engage theadjacent straight edge 14 of the casing member 13. A suitable I marker,such as a pencil,'1nay then be drawn along the straight edge -6 to markthe exact line for cutting the .base board or sawing the end of the sameoff whereby it willbe accurately and closely fitted against the edge 14of the side frame member 13.

V In Figure 6, the gauge is. shown inuse for marking a side member 15 ofa window casing or frame, in which case the memberbr i board 15 istemporarily supported at its bot- 1 bottom edge of the frame member 17.The

tom upon the bottom'member 16 of the window frame, while its upper endis swung against the upper member 17 of said frame.

per end of the casing member 15 and pushed upwardly until the abutments7 engage the pencil vor other marker is then drawn along the' straightedge 6, which is uppermost, so as to mark the exact line where'the framemem-- ber 15 is'to be sawed off to accurately fit it between the framemembers 16 and 17. p

I As shown in Figuree, the side member 1300 lower end with apart 18whose outer edge projects or is offsetoutwardly of themain straight edge14a of said side member 13a of the door frame or casing. As this memberor part 18 is usually of considerably less height than the length of themarking bar 5, the

abutment 7 which is uppermost cannot be engaged with the adjacentedgeofthe part or member 18 for properly plumbing the gauge so that a line maybe properly marked on. the base board 1200 for accurately fittingthelatter against the adjacent outeredge of said memvide the same with alongitudinally adjustable her or part 18. In order to adapt the gaugefor proper use under these conditions, I- proabutment or contact. Asshown, this adjustable contact consists of an angular strip of metalproviding an attaching arm 19 adapted to be flatly disposed againsttheinner face of the marking bar 5 transversely of the latter 7 andprovided with a central opening 20 to receive a clamping bolt 21 whichalso passes slot 22preferably extends substantially from through acentral longitudinal elongated slot 22 in the marking bar 5 and receivesa clamping nut 23 by which the adjustable contact is fixed in any of itsadjusted positions. The

Y end to'end of the marking bar 5 so that the adjustable contact may beemployed in conjunction with eith'erend fixed contact or abutment 7 atany required distance from the same.

Theangular strip from which the adjust-able contact is formed alsoprovides a contact arm or abutment member 24L projecting at rightvention as claimed.

angles to the attaching arm 19in the-same direction as the abutments 7and attached to the marking bar 5 so that its outer face isin the sameplane with the straight edge 6. Any suitable means may be provided formaintaining the adjustable abutment againstrotation about the bolt 21andwith the outerface of j the contact arm 24 parallel with the plane ofthe edge 6, such as outwardly projecting lugs 25 on the upper and loweredges of the at taching arm 19 adapted toslidably fit in thelongitudinal slot 22 of themarking bar 5-.

V In the use of the invention as shown in Figure the gauge is positionedas shown and the upper fixed contact '7 is located above the top'oftheframe part 18, the gauge maybe properly plumbed for utilizing thestraight edge 6 in markingfa lineon the base board parallel withtheouter edge of the frame part 18, whereby an, accurate fit will be hadwhen the base board is sawed off I along this line marked thereon. IObviously, the adjustable abutment maybe readily adjusted upon looseningthe nut'23, whereupon the same may be secured in the desired adj ustedposition by again tightening said'nut.

The gauge constructed as above described is simple and durable inconstruction, economical to manufacture, and capable of being readilyplaced into practical and efficient use,

Minor changes may be made without de parting from the spirit and scopeof the in What I claim as new is: 1 1. A marking gauge of the characterde;

scribed, comprising a marking'barfhaving a straight longitudinal markingedge and a .pair of fixedprojecting end abutments, said marking barbeing adapted to extend across. the board to bemarked and to'projectbeyond a the oppositeedges of said board to permit the" end abutments toengage the edgefof the :board or object to which thefirst mentionedboard is to be fitted, anda further abutment carried by and adjustablelongitudinally of said marking bar, said adjustable abutment beingadjustable substantially from'rend to end of said marking bar forselective. cooperation with either one of said'fixed end ments,substantially as described.

abut- 2. A marking gauge for the frames of door casings and the likecomprising a sheet metal marking bar 'having a straight longitudinalmarln'ngedge and provided withend portions bent at right angles to thebody' portion thereof to form end abutments, the marking edge 7 face ofsaid contact arm of the adjustable abutment and the marking edge of saidmarking bar being in the same plane.

, 3. A marking gauge for the frames of door casings and the likecomprising a sheet metal marking bar having a straight longitudinalmarking edge and provided with end portions bent at right angles to thebody portions thereof toform end abut1nents,'the marking edge of saidbar and the adjacent side edges of said fixed end abutments being in thesame plane, and a further abutment carried by and adjustablelongitudinally of said marking bar, said adjustable abutment comprisingan angular strip of metal having an attaching arm and a contact arm,said marking bar having a longitudinal elongated slot extendingsubstantially from end to end thereof, a clamping bolt extending throughthe attaching arm of said adjustable abutment and the slot of themarking bar for slidably connecting said adjustable abutment to thelatter, the outer face of said contact arm of the adjustable abutmentand the marking edge of said marking bar being in the same plane, theattaching arm of said adjustable abutment having projecting lugs on theside edges thereof engaging in the longitudinal slot of said marking barto prevent turning of said adjustable abutment about said clamping bolt.I

In testimony whereof I affix my signature.
